STAMPING OR PRINTING DEVICE.

Application filed August 17, 1927, Serial No. 213,649, and in the Netherlands July 23, 1926.

The present invention provides a printing stamp which can, in a simple manner, he arranged to make any impression desired.

According to the invention the device consists of a body with a curved surface, to which a covering of felt or similar material is attached, whilst over this covering there is arranged a strip of linen adapted to be dampened with ink and covered by a strip of pattern paper (wax paper).

Said device is particularly suitable for stampinghand-written matter, including signatures. The text or pattern to be stamped or reproduced is cut into the pattern paper with the aid of a needle or pen. or by means of a typewriter, whereupon the paper is stretched over the curved surface of the body and secured in position. After the desired number of copies has been taken the strip of 0 pattern paper is removed from the body and either kept for any further copies that may be required in the future or destroyed. This latter feature is of importance especially in connection with the use of the stamp for the reproduction of hand-written matter. signatures, etc, because, if the pattern paper with its hand-prepared matter is destroyed after using the stamp, misuse is then impossible whereas there might be misuse if a 80 permanent stamp were made and not. stored or locked away in a reliable manner.

A new sheet of pattern paper can obviously be prepared for the stamp with very little trouble.

In accordance with the invention the strip of linen, which is moistened with ink, may be fastened to the body of the stamp by means of a plate adapted to be pressed close to the body by means of screws to hold the linen strip at its ends. The strip of pattern paper may then be fastened to the body by means of a frame which fits round the aforesaid plate and removably held in any suitable manner, for example. by means of small hooks.

For indicating the correct position of a text or pattern upon the stamping surface, there may be provided in say one of the lateral surfaces and in one end surface of the device a row of holes into which markers or indicators can be inserted so that from the upper surface of the stamp it can be seen where any special part of the text is situated. This is of special importance when stamping signatures, for it is then possible to apply the signature to any definite part of a document to be signed. which is a rather ditticult matter when using the known hectograph. If the stamp is to be used exclusively for signatures it can be given the dimensions of a signature stamp in which case no means are required for indicating the position of the signature; but the stamping surface may also be given the size of a post-card, whereby it is rendered possible to impart any desired text (with or without a signature) to post-cards. In practice it has been found that at least 150 pulls can be taken without any deterioration being perceptible in the quality of the copies.

On the accompanying drawing a constructi onal form of the printing stamp according to the invention is illustrated by way of example.

Fig. 1 represents a longitudinal section of the device;

Fig. 2 is a side elevation; and

Fig. 3 represents a cross section.

The body 1 of the device is preferably made of wood and provided with a curved surface upon which is glued a covering of felt 2. Over the felt is stretched a strip of linen 3 moistened with stamping ink, said strip being clamped at its ends between the body 1 and a plate 4 screwed thereto. Above the linen strip is arranged a strip of pattern paper 5 in which the text to be printed or stamped is cut by means of a needle or with the aid of a typewriter.

In the constructional example the paper 5 is held fast by means of a wooden frame 6 provided, at each of its long sides. with a spring 7 with'which engages a small book 8 pivoted on the body 1. In one or in each of the lateral surfaces of the body 1 there is a row of holes 9 into which an indicator 10 can be inserted for the purpose of showing the position of the text in the pattern paper from the upper side of the printing device. For determining the position perpendicularly to the first surface a number of holes 11 is also provided in each shorter side of the frame 6.

It will be understood that other means may be used for the attachment of the linen and pattern paper strips without departing from the spirit of the invention.

The invention introduces a simple printing stamp with which it is easily possible, in a very cheap manner, to prepare any number of copies of any text. In addition to letters of the alphabet, figures and drawings can be nianifelded with the printing stamp and can be reproduced at any required part of the paper.

What I claim is:

1. A printing stamp including a body having a curved surface covered with felt or similar material, a strip of linen fastened over the felt material and adapted to be moistened with ink and covered by a pattern strip, afastening plat-e securing the linen strip, screw means securing the plate upon the body, a frame fitting about the faster.-

ing plate, and means removably retaining said frame in place.

2. A printing stamp according to claim 1 characterized in that in at least one of the side and end surfaces a number of holes is arranged in such manner that by means of markers or indicators inserted in the holes the position of the text upon the printing 20 surface can be clearly determined.

In testimony whereof I affix my signature.
